Lens module, by further optimization of polarized light distribution design, effectively improve the road

The average intensity of illumination, reduced the zebra effect and improves the visual effect.

3, driving power supply:

Adopts special LED drive power, wide voltage high precision constant current technique, set

There are multiple protection, short circuit, overvoltage, high temperature resistant lightning surge disturbance degree of 4 kv, or mention

High safety standards. + 55 ℃ to 40 ℃ - may be normal and stable work, region

Widely used environment.

Q:What are the necessary tests for the factory inspection of the LED street lamp?: Is a common Street shell is an aluminum plate arranged above the inside a lot of 3W or 1W beads with lens

Q:What is the problem of flashing LED street lights on the side of the road?: Check whether the current limiting resistor in the circuit has changed, or whether the current of the power supply is off the rated value. If it's a different LED flash, it's a LED quality problem that needs to be replaced.

Q:Who knows LED street lamp warm white light and positive white light have what difference, how should choose?: If the power is the same, the brightness of the white and warm white light should be the same.

Q:What is the role of heat phase change material on a LED street light?: Mainly to play the role of heat dissipation! I don't agree with that upstairs. The heat dissipation of LED street lamp can be solved by some auxiliary things. For example, a small fan with a stronger coefficient of heat is used as a shell...... And so on, these can solve the problem of heat dissipation!

Q:What is the design height and illuminance of LED street lamps?: 1, the first screenshot of table 5.1.3, Weff means: effective width of the road.2, the above lamps refer to conventional lighting, the so-called regular lighting is the lamp installation height of 15 meters below the lamppost.3, light cut type refers to: the maximum light intensity direction of the lamp and the vertical axis of the lamp included angle between 0-65 degrees.4, half light type refers to: the maximum light intensity direction of the lamp and the vertical axis of the lamp included angle between 0-75 degrees.

Q:What's the main reason for LED street lights?: There are many reasons, but the most important reason is the poor quality of the controller

Q:LED street lights generally use how many W, how much density is more appropriate?: Most of the 1W with LED, taking into account the heat and street size, the general LED spacing about 30MM is more appropriate

Q:What is the LED lamp light?: LED is English light emitting diode (light emitting diode) abbreviation, its basic structure is a electroluminescent semiconductor chip light emitting materials, with silver glue or glue curing to the bracket, connecting a chip and a circuit board and then with silver or gold, then sealed with epoxy resin around, to protect the internal core role finally, the installation shell, so the seismic performance of LED lamp is good.

Q:Who knows the relationship between the number and weight of LED street lamp: In fact, there is no relationship at all. The weight of the street lamp: a large part of the relationship between the shell and the heat sink inside it.

Q:Solar LED street lamp, how much is a set of solar street lamps wholesale price?: Solar street lighting controller is divided into two buck and step-up, Buck 50 yuan, step-up 80 yuan, the warranty for three years. Yangzhou is the largest production base of street lamps in China, which can be visited by manufacturers.
